Photosynthesis

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose, using carbon dioxide and water.

Front

What are the two main stages of photosynthesis?

Back

The two main stages of photosynthesis are the light-dependent reactions and the light-independent reactions (Calvin Cycle).

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is a green pigment found in chloroplasts that absorbs light energy, primarily from the sun, which is essential for the photosynthesis process.

Front

What is produced during the light-dependent reactions?

Back

During the light-dependent reactions, ATP and NADPH are produced, along with oxygen as a byproduct.

Front

What is the Calvin Cycle?

Back

The Calvin Cycle is a series of light-independent reactions in photosynthesis that use ATP and NADPH to convert carbon dioxide into glucose.

Front

What is the significance of the electron transport chain in photosynthesis?

Back

The electron transport chain is a series of proteins that transfer high-energy electrons, leading to the production of ATP and NADPH during the light-dependent reactions.

Front

What is the primary function of chloroplasts?

Back

The primary function of chloroplasts is to capture light energy and convert it into chemical energy through photosynthesis.

Front

What is the difference between light-dependent and light-independent reactions?

Back

Light-dependent reactions require light to produce ATP and NADPH, while light-independent reactions (Calvin Cycle) do not require light and use ATP and NADPH to synthesize glucose.

Front

What is the role of water in photosynthesis?

Back

Water is a reactant in photosynthesis that provides electrons and protons, and it is split during the light-dependent reactions to release oxygen.

Front

What is the overall equation for photosynthesis?

Back

The overall equation for photosynthesis is 6CO2 + 6H2O + light energy → C6H12O6 + 6O2.
